Ethylenediaminetetraacetic acid disodium salt dihydrate – Catalog Number: B2014981 (10 g)

Ethylenediaminetetraacetic acid disodium salt dihydrate is provided as a biotechnology-grade powder in a defined 10 g package (Catalog B2014981) with RT storage. The supplier designates this material as suitable for molecular biology workflows and notes that it has been analyzed for the presence of nucleases and proteases. In bench practice, disodium EDTA is widely incorporated as a chelating agent to manage free metal ions that can influence stability, background, or enzyme behavior during method development and training exercises. The clear specification set—amount, supplied-as, storage, keyword identity, and grade statement—supports straightforward SOP inclusion and inventory traceability in multi-user settings.

For qualitative studies and platform checks, a powder presentation allows accurate mass-based dosing and convenient preparation of working stocks in a laboratory’s preferred buffer system. Because the listing does not prescribe a working concentration, it is good practice to determine conditions empirically for the matrix and task at hand. Small pilot preparations that document pH and ionic strength, incubation times and temperature history, and compatibility with other components can help define an operating window while supporting reproducibility across analysts and instruments. When EDTA is used alongside metal-dependent enzymes or chromogenic systems, recording lot identifiers and time-at-temperature is useful for method transfer and future audits.

Typical research scenarios include assembling buffer systems for nucleic-acid handling where chelation helps manage divalent cations; configuring reagent panels for sample pretreatment or storage studies; and building instructional demonstrations of metal ion effects on assay performance. The biotechnology-grade note—solutions prepared using Type I ultrapure water and fine filtration—aligns with expectations for low background during optimization. Within research-only boundaries, this clearly documented disodium EDTA offering integrates smoothly into biochemical and molecular biology workflows that benefit from controlled metal-ion availability and consistent, well-recorded reagent handling.

Why researchers choose this product:

• Defined 10 g fill in powder form for precise dosing and stock preparation
• Designated for molecular biology use; analyzed for nucleases and proteases
• Specified RT storage streamlines inventory handling
• Concise, documentation-friendly fields (amount, supplied-as, storage, keywords, grade)
• Versatile chelating agent for metal-ion management in research workflows

This product is for Research Use Only (RUO). It is not intended for diagnostic or therapeutic use.
